Private Sub mnuFileOpen_Click()
  If edit.DirtyDialog Then edit.FileOpen
  dropFile.Text = edit.filename
  SetTextMode edit.TextMode
End Sub

After checking that the current file is saved, call the FileOpen method of the XEditor object. FileOpen in turn calls VBGetOpenFileName:

Function FileOpen() As Boolean
  Dim f As Boolean, sFile As String, fReadOnly As Boolean
  f = VBGetOpenFileName( _
    FileName:=sFile, _
    ReadOnly:=fReadOnly, _
    Filter:=FilterString, _
    Owner:=hWnd)
  If f And sFile <> sEmpty Then
    TextMode = Not IsRTF(sFile)
    LoadFile sFile
    If fReadOnly Then Locked = True
    FileOpen = True
  End If
End Function

Pass the result to the LoadFile method.
